The subject of the invention is an ocean freight transportation arrangement, which arrangement comprises multiple transportation equipment units, such as a container or similar, especially intended for shipping loose materials, to enable transportation of loose materials on ocean vessels, such as in a cargo ship's, barge's, or similar vessel's cargo hold. The upper part of transportation equipment unit (X) comprises a tub structure with an upper part that is open or can be opened, and where the midsection, vertically h and from a cross-sectional perspective, tapers off toward the bottom and is connected from the lower edge to the bottom part, which means that the tub structure makes it possible, first, to transport the transportation equipment containing primarily loose cargo, stacked one on top of the other, and, second, to store empty transportation equipment units on top of each other, and, at least partially, stacked in a pile.
